Application filed October 3,

To all 'iuhom it may concern:

Be it known that I, JOHN A. CURRY, a citizen of the United States,residing at Key est, in the county of Monroe and State of Florida, haveinvented certain new and usethe folowing to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specifier tion.

My invention relates to locks and'has for its object to provide a noveldevice of this class to be used on doors and the like.

A further object of my invention is to'provide a lock which isparticularly simple in its construction and designed with a view to Withthese objects in view my invention consists in the novel constructionof'the sliding bolt tumbler and the arrangement providing for theoperation of the tumbler by means of the key; and my invention alsoconsists in the novel construction which provides for dis-engaging thetumbler from the bolt by a sliding key.

My invention also consists in certain other novel features ofconstruction and'in combination of parts which will he first fullydescribed andafterwards specifically pointed out in the appended claims.

Referring to the accompanying drawing. Figure 1 is a verticallongitudinal sectional view through thelock easing. Fig. 2 is a verticaltransverse seotionsLview taken on line 2 -2 of Fig. 1, and, Fig. Clis ahorizontal seclionai'view through the casing above the lmlt. I

Like numerals ol' rhl'erence indicate the same'parts throughout theseveral figures in which,

I indicates the casing, 2 the bolt, 3 thcslidknobs 5 carried on aspindle (5 of usual form which spindle passes entirely through thecasing carrying within the casing a small drum 7, secured to said drumin any convenient manner and as shown in Figs. I and 3 is a flexiblelink 3 which is connected to the boil. 2. Suitable guides !l areprovided for the bolt 3 while a coil spring H) is arranged l behind thebolt 2 normally holding said bolt in on extended or lm-king position asshown l Specification of Letters Patent.

in Fig. 1. The tumbler 3 is bifurcated as shown in Fig. 2 comprisingbile two exten-' sions 11 and 12, said tumbler straddling the bolt 2,which bolt is provided with grooves 13 and 14 on each side thereof toreceive theextensions 1 l and 12 of the tumbler 3. Suitable guides 15are provided on the casing 1 within which the tumbler 3 slides. Aooilspring 16 above the tumbler 3 is arranged and exerts a downward pressureon the tumbler 3 in order to hold the same in engagement with the boltas shown in Fig. 1.

An opening 17 is provided on the bottom edge of the casing 1 directlybelow the extension 11 of the tumbler 3, while the groove 14 (Fig. 3) inthe bolt- 2 is elongated. n 'slot 18 is also provided in one face of thecasing: directly in front of the tumbler 3 so that a knob or projectioncan be )rovidcd on said tumbler to extend through the casing formanipulation of the tumbler without'the use of" the key; thus the lockcan be used in the capacity of a latch.

liaving thus fully described the several )arts of my invention itsoperation is as follows: The normal position of the bolt and tumbler isshown in Fig. 1. In order to illustrate the bolt out of its lockingposition the key 4 is inserted in the opening 17 on the bottom edge ofthe'casing and forced rip-'- wardly entering the groove 14 in the bolt 2and engaging the lower end of the extension 11 of the tumbler 3, thusforcing said tumbier out of engagement with the bolt 2 as shown in Fig.2. When the tumbler is in this position either of the knobs 5 can beturned, which through the medium of the flexible link 8 draws the boltinwardly and out of lockin osition. it is of course (6- 9C dent that theeys can be made in a vast number of forms and shapes so that each lockwill require a different key in order to oporate the same. Whenutilizing the look as a latch the tumbler 3 can be provided with a.

small knob or projection extending through theeasing, by raising theknob or projection the tumbler will be carried out of engagement withthe bolt 2 and the bolt 2 then operated by one of the knobs 5. Theelongated groove 14 in the bolt 2 ailows the bolt.

to slide while the key is still within-the slot as is clearly evidentfrom Fig. 3,. Having thus'fully described my invention what 1 claim asnew and desire to secure by Letters Patent of the United States ls,- l.-A lockcomprising a slidingbol-t, a slid- News ms-saw. no...
